iPod Touch for dummies - restricting friends

Despite my DD (10) being told to only accept requests for contact from people she knows, and despite a schoolfriend being contacted by a pedophile, I still found out today that she has communicated with someone who has sent an explicit photo ( Police are coming to see us tomorrow).

So, I've locked her Touch by Settings/General/Restrictions/set password and then at Game Center turned off adding friends. Does this mean she has to ask me to unlock it when she wants to add a friend on instant messaging such as Touch and Kik, or is it just within Games like Draw Something?
